Definitions

  • the invention relates to an anti-skid chain for vehicle tires with an inner holder and an outer holder having at least one division point bridged by a tension cord, as well as running net elements arranged between the two holders with chain strand sections oriented obliquely to the running direction, in which the dividing point of the outer holder between the points of application of two in the running direction successive chain strand sections of the running network oriented obliquely to the running direction is arranged.
  • the invention has for its object to provide an anti-skid chain of the type under consideration, in which the tension cord is designed and guided so that when mounting the chain on tires of a certain size range regardless of the size of the distance between the end points delimiting the division point a running network configuration can be maintained in the outer bracket, which guarantees that there are always chain links in the area of the tire's ground contact area.
  • This object is achieved according to the invention in that the two chain strand sections running to their points of attack lying on both sides of the division point of the outer holder are viewed apart in the direction of the outer holder so that one of these two chain strand sections forms part of the tension strand and that the tension strand is guided, under each change of direction, through two deflections which delimit the division point in the area of the outer holder.
  • the anti-skid chain according to the invention has the advantage that its anti-skid properties do not depend on the size of the distance between the end points of the outer bracket in the area of the dividing point and that the part of the tension cord to be kept in the area of the outer bracket with regard to the use of a chain strand section of the running network Chain for tensioning or expanding purposes can be relatively short.
  • FIGS. 1-5 show an anti-skid chain with essentially Y-shaped mesh elements as well as an outer bracket 1 and an inner bracket 2.
  • the inner holder 2 is formed by a one-piece, spring-elastic ring which is provided with a closure 4 in the region of a division point 3.
  • the spring-elastic ring is spread open when fitting the anti-skid chain and put over the vehicle tire 5. As soon as it has passed the tread of the tire, it can be released and then automatically spring back into its closed shape.
  • the closure 4 has the task of keeping it in this form.
  • the outer bracket 1 and a tension cord 6 serve to tension the anti-skid chain.
  • the tension cord 6 bridges a division point 7 of the outer bracket 1, which is delimited by deflections 8 and 9, which are fastened to the opposite ends of the outer bracket 1.
  • the division point 7 of the outer bracket 1 is between the An Handles of two chain strand sections 10 and 11 oriented obliquely to the running direction are arranged on the outer bracket, the point of attack of the chain strand section 10 on the outer bracket 1 being formed by the deflection 8 and the point of attack of the chain strand section 11 on the outer bracket 1 being formed by a so-called side hook 12.
  • the ends of the chain strand sections 10 and 11 facing away from the outer holder 1 are brought together in a node 13, from which a chain strand section 14 extends to the inner holder 2.
  • the chain strand section 10 forms part of the tension strand 6 and, as a type of tension reserve, facilitates the expansion of the outer holder 1, as can be seen from FIG. 4.
  • a hook 15 arranged at the end of the tension cord 6 is suspended in a link 16 of the outer holder 1.
  • the dimensions of the hook 15 are preferably chosen so that the hook cannot pass a guide ring 17 connected downstream of the deflections 8 and 9.
  • the guide ring forms a safeguard against the noise of the tension cord 6. It is possible to design the guide ring or one of the deflections 8 or 9 as a lock for the tension cord 6. This can be done, for example, by designing the opening of the deflection 8 not in the shape of a circle but in the form of a keyhole.
  • FIG. 6 shows an anti-skid chain with a modified network configuration. While Y-shaped running net elements are used in the particularly advantageous exemplary embodiment described first, double trapezoidal anti-skid elements are used in the anti-skid chain according to FIG. 6.
  • the chain strand sections 10 and 11 therefore do not converge here to a common node, but rather end in the area of the tread at nodes 23 and 24, which are connected to one another by a track piece 25 and to the inner holder 2 via further chain strand sections 26, 27. Otherwise, the structure of the second anti-skid chain largely corresponds to the structure of the anti-skid chain according to FIGS. 1-5 speaking parts were therefore used the same reference numerals.
  • a tension spring 28 is arranged in the region of the end of the tension cord 6 in the second embodiment, specifically between the hook 15 and a stop ring 29, the outer dimensions of which are larger than the inner dimensions of the guide ring 17.
